Specification of Letters Patent Patented Dec. ti l, 1915.

Application filed 1T anuary 8, 1915. Serial No. 1,105.

To all whom it may concern:

Be it known that I, Lnnor A. WESTON, a citizen of the United States of America, residing in Adams, county of Berkshire, and State of Massachusetts, have invented certain new and useful Improvements in Joint-- T he invention is particularly designed for use in connection with my improvement in the method of and apparatus for forming pipe joints, on which the application for Letters Patent of the United States was filed October 6, 1914, Serial No. 865,287.

T his invention. broadly, comprises a flexible band of suitable material, as galvanized sheet iron or tin, to which is attached in any suitablemanner a strip or ring of packing material, as hemp. in rope-like form, or a strip of felt, as desired. llhis band is attached to the end of the tile pipe that is inserted into the bell of the adjacent tile and is provided with means to prevent its slipping away or rearward from the end of the section of tile during the insertion of the same into the bell. lhe purpose of this packing is to prevent the cement or other water-tight joint forming material from working its wavthrough the bell into the inside of the drain pipe and thus destroy in a large measure the usefulness of the drain Or sewer pipe. I

Another object of this packing material is to furnish means whereby the joint is permanently closed all the way around. particularlv at the bottom where. as often happens. the tile pipe lies in flowing water in the trench andthe cement. on account of the water in the trench often thoroughly prevents the cement from hardening as it should. and often runs out at the lower side of the bell resulting in a defective joint and allowing the contents of the pipe to escape.

Referring to the drawings: Figure l is anend elevation of the device detached from the end of the pipe and showing the packing strip of hemp in rope-like form, that is attached to the band by means of the struckup clips and also the internally and radially projecting ears or lugs that are designed to engage the end of the tile pipe to prevent the band from. slipping back on the tile when it is inserted into the bell; Fig. 2 is a detail sectional view showing the manner of locating or arranging the band on the end of the tile'pipe so as to prevent its slipping out of position when the section of tile is inserted in the bell; Fig. 3 illustrates in side elevation the adjacent ends of two sections of tile pipe after the end bearing the packing ring is inserted into the bell portion of the adjacent section; Fig. 4 shows a modification of the device in which a strip of felt is employed instead of the hemp rope-like ,form of packing; Fig. 5 is a view in side elevation showing the modified structure shown in Fig. 4 in place on the end of the tile; Fig. 6 is an endview of Fig. 5: Fig. 7 is a detail sectional view on the line 7-7 of Fig. 4; Fig. 8 is a detail sectional view on the line 8-8 of Fig. 4; Fig. 9 is a modification of the means for attachin the ends of the flexible strip together, and Fig. 10 shows an assembled view of two sections of tile pipe with the modified device shown in Fig. 4 in place.

Referring to the drawings in detail: 1

designates the and portion which is formed of suitable width of thin sheet material, the edge of which is formed with struck-up ears orprojections 2 and 3.

4 designatesa strip of packing material, as hemp rope. that is attached to the band 1 by means of the clips 3 which are bent over to securely retain the rope 4 in place. Attached to the ends of the band 1 are wires 5, by means of which the band which carries the strip of packing material may be readily attached to the tile. llwo sections of the tile pipe are indicated in Figs. 3 and 10 at 6 and i 7, figure 6 showing thejoint packing device in place prior to its insertion into the hell 8 of the section 7.

Reference to Figs. 2 and G clearly shows an important feature of my invention which prevents the band 1 from slipping back on the section 6 of the tile, as this section is pushed into the bell. Thisfeature comprises the struck-up projection 2, which engages the end 6 of the section of ,tile 8.

fication of the device shown in Fig. 1, the

9 lower or bottom Referring to Figs. 3 and 10 which show the position of the packing material after the insertion of the section 6 into the section 7, it will be observed that the band of pack-- ing materiahis pushed completely to the seat 7 of the bell, whereby, when the joint is completely filled in with cement filling, at the portion 9, the same cannot escape or flow past the packing material on the end of the section 6 into the interior of the drain pipe. I

It will be seen that I have provided a simple and very inexpensive device for packing the joint and. one which the workman can readily apply to the end of the section;

cement will not properly fill the portion 9,

but will be scattered and flow into the interior ofthe drain pipe, thus preventing making a water-tight joint.

Referring to Fig. 9 which shows a modification of the manner of attaching the two free ends of the band 1: 10 designates a reduced portion of the flexible bandwhich is designed to enter one of the openings 11 in the adjacent end, whereby, after the strip 10 is passedthrough one of these openings, it

can be bent over and securely lock the band 1n place, as readily understood.

Referring now to Fig. 4 which is amodiband 1, instead of being flat as indicated in Fig. 2, is made with a flaring edge 1 as indicated in Figs. 7 and 8, and placed over this edge is a flat strip of felt 4. This strip of felt is attached to the metal strip 1 by means of the bent over clips 3'. Radial projections 2 extend inward, as in Fig. 1, for

engaging the end of the tile'to prevent the device from slipping rearward thereon when the title is inserted into the bell. This flaring construction and strip of felt thereon operates in the same manner as the rope 4, to prevent the'scape of cement past the end of the tile into the interior of the pipe. The pressure of the cement in the space 9 would act to force the strip of felt tightly against the inner surface of the bell as readily understood.

It is clearly within the province of my invention to do away with the struck-up portions 3 and use other means of attaching the rope 4 to the band 1, as this can readily be accomplished by short pieces of wire whichcan be passed around the band and the ends twisted together to hold the same in place. I do not, however, wish to be understood as limiting myself toany particular form of at- 'taching device to retain the packing material 1 4L or 4 in place on the band, nor to any particular formof projection which engages the end 6 of the tile-pipe to prevent its slipping back during the operation of inserting this end of the tile pipe into the adjacent bell of the next section.

Referring to the construction shown in Figs. 4, 5, 6, 7 8, and 10, the flaring edge 1' of the band is slitted as indicated at 1 The purpose of slitting this edge is to permit it.

to readily adapt itself to the exact form of the inner surface 8 of the bell 8 of the tile.

It is a well known fact that the inner surface 8 of a section of tile is slightly tapering surface8 when the adjacent tile section 6' is pushed into the bell, as shownin Fig. 10, whereby the extreme outer edge 1 forms a tight joint between the band and the inner surface 8. When the cement is poured into the space 9, it cannot, therefore, escape by the edge 1 into the adjacent section. This is a very important feature of my invention as it permits the flexible band on which the packing material is placed to readily adapt itself to any irregularities of the surface 8.

It should be stated that the packing material 4' as shown in Figs. 5, 7, and 8, extends slightly beyond the edge 1 of the slitted portion 1 so that, when the section of tile having the packing ringthereon is inserted into the bell 8, the edge of the packing material is tightly wedged between the extreme outer edge 1 and the inner surface 8 of the bell and then, when the cement is poured into the space 9, it cannot escape past the packing material into the inside of the pipe. It

will also be'observed that this packing materia comprises a flat strip substantially the same width as the band of flexible material.

What I claim is:

1. A packing device for joints comprising a strip of packing material, a band of sheet material provided with outwardly struck-up projections for engaging the packing strip to secure thev same to the band and inward projections arranged to engage a pipe end, the said band being provided at both ends with fastening elements.
